PRINTING ATTACHMENT FOR PHOTOPRINTING-MACHINES.

Application led .Tuly 16. 1919.

To @ZZ whom it may concern Be it known that I, THOMAS G. Coornn, a citizen ot the United States, and a resident of Jefferson City, in the county of Cole and State of Missouri, have invented a new and Improved Printing Attachment for Photopri1iting-l\/iachines, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved printing attachment for photoprinting machines arranged to automatically print identification characters and other legends on the back of the sensitized printing sheets during the printing thereof, with a view to identify the prints of each particular job, preferably by printing the same number thereon, and also to print the photographers name on each print. Another object is to enable the operator to set the identifying means for each particular job. Another object is to provide a printing attachment which can be readily applied to an ordinary photoprinting ma chine as now generally constructed. Another object is to provide a printing attachment which is simple and durable in construction, not liable to get out of order and arranged to require no attention on the part of the operator during the printing of the sheets for a given order.

`With these and other objects in view, the invention consists of certain novel construction, as hereinafter shown and describedl and then speciiically poitned out in the claims.

A practical embodiment ot the invention is represented in the 4accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts iii-all the views.

' the improved printing attachment and with i sheet 13 of the printing paper is pressed in firm contact with the negative by a door or plate 14 hinged to a back section 15 provided with arms lbmounted to swing on a transverse rod 17 attached to brackets 18 -fastened to the top of the cabinet 10. The door 14 is provided on top with cam plates 20 having cam slots 21 engaged by a transverse rod 22 held in the free ends of side arms 23 fulcrumed on the rod 17. Links 24 connect the side arms 23 with a pedal 25 mounted on the lower end of the cabinet and under the control of the operator. A spring (not shown) is coiled on therod 17 and engages the arms 23 to normally hold the latter in uppermost position, as shown in Fig. 8, thus holding the door 14 in open position and with the treadle 25 raised. After the negative 12 and the sheet 13 of printing paper are in position on the glass plate 11, and the operator presses the treadle 25 then the door 14 swings downward to cover the glass plate and press the sheet 13 of printing paper in firm contact with the negative 11. It is understood that the interior of the cabinet is provided with a suitable source of light to insure proper printing of the sheet v 13 of printing paper. The under side of the door 14 is provided with the usual felt facino- 26.

The door or plate 14 and its facing 26 is provided with registering openings 30 and 31 throiwh which extend a series of numbering wheels. preterablv three in number and marked 36 and 37. The numbering wheels 35. 36 and 37 are mounted to turn an enlarged portion 38 of a shait 39 iournaled in a numbering wheel trame 40 provided on the top with a stem 41 slidinfrly engaging a main trame 42 secured on the top of the door 14. A spring 43 is coiled on the stem 41 and is interposed between the top of the frame 40 and the frame 42A to press the numbering wheel frame downward to engage the bottoms of the numbering wheels 35, 36 and 37 with the back of the print 13 to makea proper impression thereon to provide the'print with an identification number, as hereinafter more fully explained. On the upper threaded end of the stem 41 screws a nut 44 resting on the top of the main frame 42 to limit the downward movement of the numbering wheel frame 40. By adjusting the nut 44, the numbering wheel frame can be readily raised or lowered so as to bring the bottom e printing faces of the numbering wheels 35, 36 and 37 in proper printing relation with the print 13. vThe ends of the shaft 39 extend into vertical guideways 45 formed on the main frame 42 to prevent turning of the numbering wheel frame 40 and to guide the same when adjusted in an up and down direction. The nut 44 is locked in lplace by a set screw 46 after the desired adjustment of the numbering wheel frame 40 has been made. In the opening 31 adjacent the bottom portion of the unit numbering wheel 35 is arranged a printing block V50 glued or otherwise 'secured'to the under side of the door 14 and provided at its bottom Vwith printing characters 51 representing a desired legend .such as a photographers name .or the'like. Thus when an impression is made, the numbering wheels 35, 36 and 37 print an identification number on the back 'of the print 13 and the Characters 51 print a legend on the said back adjacent the iden- 4 tification number- "1 -ln'order to automatically ink the printing face ofthe numbering wheels 35, 36 .and 37 and that of the printing block 50, use-is made of an inking pad 60 mounted in a holder 61 detachably held byV aspringpressedbutton 62 -on the free end of an L- --shaped arm 63 pivoted on -a rod 64 held ina i i. bracket 65 attached to the free end of the door 14. Springs 66 are coiled on the rod 64 and engage a crossbar 67 forming part fof thearm 63 to normally holdthe latter in 'inking position, that is, with'the pad 60 in :linking contact with the printing face of f thevnumbe-ring wheels 35, 36 and 37 and the vprin-ting face of the block50, as illustrated in Figs. 1, 2, 3 and 5. On the arm 63 is -pivoted a-l-ink 70 engagedby a ring 71 held on achain or other flexible/connection 72 .extending over-va guide wheel 73 mounted to" rotate loosely on the rod 64. The flexible -connection 72'extends upwardly and rearwardly and its upper end connects by `a ring 74with a collar 75 having' a limited turning motion on a crank arm 76 forming part of the rod 22 .previously mentioned.

When the several parts are in the position shown in Fig. 8 and the operator presses the treadle 25 then a `downward swinging movement is given :to the Vside arms 23 whereby a downward swinging movement is given to the door 14 by the rod 22 traveling in the cam slots 21 thus causing the door to swing faster than the arms 23 whereby a pull is exerted on the flexible connection 72 thereby imparting a swinging motion to the arm 63 to swing the pad 60 out of engagement with the printing faces of the numbering wheels 35, 36 and 37 and the printing face of the block 50, and at the same time the arm 63 and its pad 60 swing out of the path of the door 14 thus allowing the latter to close with the arm 63 and its pad 60 in raised position, as indicated in Fig. 7. When the operator releases the treadle 25 then the door 14 returns to uppermost position and in doing so the pull on the flexible connection 72 is released to allow the spring 66 to swing the arm 63 downward and rearward into inking position with the printing faces of the numbering wheels 35, 36 and 37 and that of the block 50. It is understood that'each of the prints of a particular job have printed thereon the same identification number, and for the next job it is desirable to reset the numbering device with a view to print the next following number on the prints of the second job from those of the Vfirst job. 1n order to enable the operator to quickly and conveniently set the numbering wheels, the following arrangement is made: The numbering wheels 35, 36 and 37 are provided with ratchet wheels 80, 81 and 82, each provided with a cut-out portion 83 extending approximately between adjacent teeth, as will beunderstood by reference to Fig. 3. The ratchet wheels 80, 81 and 82 are adapted to be engaged by pawls 84, 85 and 86 of different length and secured to a pawl carrier 87 `mounted to swing on a pivot pin 88 held in a yoke 90 mounted to'swing on the shaft 39 as the fulcrum. A spring 91 is coiled on the pivot 88 and bears on'the pawl Acarrier 87 to swing the said r carrier toward the ratchet wheels 80, 81 and 82. The pawl carrier 87 is also provided with a hande 9 2 adapted to be taken hold of by the operator for swinging the pawl carrier away from the ratchet wheels whenever it is desired to do so. The yoke 90 has a limited swinging movement and for this purpose the yoke is provided with a slot 95 Figs. 1 and 2) into which project a stop pin 96 held on 40. r1`he yoke90is Aprovided on each of the side arms with a single tooth 100 extending between two teeth 101 formed on the free ends of a two-armed lever 102 fulcrumed at 103 on the corresponding side of the numbering wheel frame 40. The lever 102 is provided with a suitable handle 104 and is pressed on by a spring 105 (see Fig. 3) to normally hold the lever 102 and the yoke 90 in the position shown in Fig. 1, that is, with the upper ends of the slots 95engaging the pins 96. When it is desired to advance impart a swinging movement the unit numbering wheel, it is only necessary for the operator to take hold of the handle 104 of the lever 102 and swing the same upward toward the main frame 42 to to the yoke 90 whereby the pawl carrier 87 is carried along and the latters pawl 84 engages the ratchet wheel and turns the same and with it the unit numbering wheel 35 to the next number. When this has been done, the operator releases the handle 104 to allow the spring 105 to return the lever 102 to the position shown in Fig. l. It is understood that during this return movement of the yoke the pawl 84: glides over the corresponding tooth of the ratchet wheel 80. lNhen the ratchet wheel 8O and consequently the numbering wheel 35 have made a revolution then the pawl 84: extends into the cut-out portion 83 of the ratchet wheel 80, thus allowing the next following pawl 85 to engage its ratchet wheel 81, and when the lever 102 is swung upward by the operator for the next resetting of the numbering wheels then both the unit wheel and the tenth wheel are turned to the next number. rThe same operation takes place after the numbering wheel 36 has completed a revolution. When this takes place both pawls 84: and 85 extend in the cut-out portion 83 of their respective ratchet wheels 80 and 81, thus allowing the third pawl 86 to move into engagement with its ratchet wheel 82, and when the lever 102 is next swung upward the three numbering wheels are shifted into the next number.

From the foregoing it will be seen that by the arrangement described, the identification characters and other legends are printed on the back of a photoprint during theV printing thereof with a View to identify the prints of each particular job. It will also be noticed that the operator in charge of the machine can readily set the numbering device to a following number after the completion of a job. It will further be noticed that the printing attachment can be readily applied to photoprinting machines as now generally constructed without materially altering the construction thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
